Comparison of TOROID power supply and ELECTRONIC power supply for LEDs

Advantages of TOROID against ELECTRONIC power suppy:

-         absolute efficiency of toroid 99%

-         reliability – lifetime unlimited

-         failure rate in orders of per mil

-         posibility of shortime overloading au to 30%

-         indoor and outdoor use at extreme temperatures

-         IP 65

-         Stable secondary current in case of unstable primary current

-         Secure against short circuit by means of reversible fuse

-         Safe voltage 12V

-         Optimal for outdoor difficult accessible signs

-         Does not interfere TV and radio broadcasting

-         Possible to choose AC/DC or DC voltage

-         lower price

-         built in rectifier with filter

Disadvantages:

-         bigger weight

Advantages of ELECTRONIC power supply:

-         smaller dimensions

-         small weight

Disadvatages:

-         higher fialure rate

-         possible interference of TV and radio broadcasting

-         lifetime max. 20000-35000 hours

-         when overload transformer immediately turns off

-         due to higher failure rate not ideal for difficult accessible outdoor signs

-         higher price
